Layout of systems for
vibration isolation and earthquake protection
For the design and layout of
systems for vibration isolation there have to be distinguished
two basic cases in general:
- active isolation
Here the dynamic excitation has its origin on the
component which has to be isolated.
Typical applications are machines with rotating or
oscillating masses causing unbalances which are
disturbing the surrounding environment.
- passive isolation
In this case the vibration isolation system shall protect
the isolated component from disturbances which will be
induced from other aggregates outside.
Examples for this can be found on the field of tool
machines like roll grinders. There a small disturbance
might harm the production process very severe.
But also the protection of buildings or building parts
against vibrations e.g. from railways gets a higher
relevance considering the environmental care.
The layout and calculation of
systems for vibration control is one of our main scopes of work.
To offer our clients technically
and economically optimized solutions we are in permanent contact
with the leading companies supplying vibration isolation systems.
Following different systems have
to be considered:
- systems with helical springs
- systems with air springs (point
- systems on plastics basis (area
Each system is optimized for a
special range of supporting frequency. So the choice of a
specific system depends on the actual application.
Spring elements which possess a
low inner damping can be combined with seperate or integrated
damping systems to minimize the deflection amplitudes of the mass-spring-system.
